The thioredoxin (Trx) system, including thioredoxin reductase (TrxR), regulates cellular redox signaling and tumor development. Targeting TrxR/Trx with small-molecule inhibitors shows promise for cancer treatment, despite challenges.
Area of Science:
- Biochemistry
- Cell Biology
- Oncology
Background:
- The thioredoxin (Trx) system, comprising Trx and TrxR, is crucial for cellular redox balance and signaling.
- Dysregulation of the Trx system is increasingly linked to tumor development and progression.
- TrxR/Trx represents a promising therapeutic target for novel cancer treatments.
Purpose of the Study:
- To review the structural and functional aspects of the Trx system.
- To elucidate the rationale for targeting TrxR/Trx in cancer therapy.
- To highlight small-molecule inhibitors of TrxR/Trx with potential anticancer activity.
Main Methods:
- Literature review focusing on structural details of TrxR.
- Analysis of Trx system functions in cellular redox signaling.
- Examination of small-molecule TrxR/Trx inhibitors and their mechanisms of action.
Main Results:
- The Trx system plays a pivotal role in redox signaling pathways.
- TrxR/Trx inhibitors demonstrate potential anticancer effects.
- Various small molecules targeting TrxR/Trx have been identified.
Conclusions:
- Targeting the Trx system, particularly TrxR/Trx, is a viable strategy for cancer treatment.
- Small-molecule inhibitors offer a promising avenue for developing anticancer agents.
- Further research is needed to overcome challenges in developing selective TrxR/Trx inhibitors.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
